Answer:

Answer is 13.

Step-by-step explanation:

EQ 1: y = 2x^2-x-2  

EQ2: y = x^2+3x -5

Set the two equation equal to each other:

2x^2-x-2 = x^2+3x -5

Simplify:

x^2 -4x +3 = 0

(x - 3 ) (x - 1) = 0

Solutions:

x = 3 and x= 1

Plug these values into each of the original equations and see which on gives you the highest value.

Solution set:

y={13, -1, 13, -1}

Answer is 13

John took all his money from his savings account. He spent $88 on a radio and 1/4 of what was left on presents for his friends.
gayaneshka [121]

Answer:

$968

Step-by-step explanation:

x= the money John originally had in his savings account

The statement says that John spent $88 on a radio and 1/4 of what was left on presents for his friends. This means that the remaining money is 3/4 of the total amount minus the money spent on the radio:

3/4(x-88)

Then, it says that of the money remaining, John put 4/11 into a checking account and the last remaining $420 was left to charity. Since, he spent 4/11 of the remining 3/4(x-88), the remaining is 7/11 of that and that remaining is equal to $420 that was the money left at the end:

7/11(3/4(x-88))= 420

21/44(x-88)=420

21/44x-42=420

21/44x=462

x=968

According to this, the money that John originally had in his savings account was $968.

He spent $88 on a radio: 968-88= 880

1/4 of what was left on presents for his friends: 880/4= 220

880-220=660

Of the money remaining, John put 4/11 into a checking account: 660*(4/11)=240

the last remaining $420 was left to charity: 660-240= 420

A game is played with a deck of 50 cards numbered from 1 to 50. At the end of each round, players calculate their score by addin
liberstina [14]

Answer:

28

Step-by-step explanation:

Since the score is the sum of all cards a player has, the way to make it smallest is to use the smallest cards.  So the 7 smallest cards are 1, 2, 3, 4, 5, 6 and 7.  So you want to add these up.  This gets 28
